Grove

The Grove system is a modular,  easy to use tool set (arduino compatible).  Similar to Lego, the grove system take a building block approach to building electronics systems in a easy and versatile way.   The Grove system is based of a base shield that can have many modules connected via standard connectors, all with ready to use example code.  The Grove base shield is plugged onto an arduino compatible microcontroller.  THe modules can be simple things like buttons, all the way to complex sensors like heart rate sensors.  Each Grove module comes with clear documentation and demo code to help you get started quickly.
